he new Phresh Easy Fan Controller will thermostatically adjust airflow by varying the speed of your V2 HyperFans. The Easy Fan controller has three simple dials for operation and is easier to use than previous versions. On cold days & nights the Easy Controller reduces the fan’s RPM down to a minimum to keep plants warmer and maintain just enough airflow for effective carbon filtration. During warmer temperatures, the Easy Fan Controller will raise the fan’s RPM to help cool your grow space. The differential dial allows you to run the same fan diameter Hyperfans for both inlet and outlet while easily dialling in perfect negative room pressure. The new Phresh Easy Controller can operate up to two inlet and two outlet V2 Hyperfans at once. Take control of your environment with the Phresh Easy Fan Controller.
